Rotary drilling machines are vital in foundation work, featuring intricate components that synergize for efficient operations. Let’s delve into the crucial parts that make up these powerful machines.
1. Crawler Chassis:
The foundation of a rotary drilling machine lies in its crawler chassis, comprising a walking mechanism, track tensioning device, and longitudinal beams for stability during movement.
2. Upper Structure:
Comprising the base frame, turntable, operator’s cab, engine, main and auxiliary winches, and counterweights, the upper structure is the command center of the rotary drilling machine.
3. Mast Structure:
The mast structure involves anchor frames, pulleys, upper and lower masts, and pressure cylinders. It serves as the pivotal turning mechanism, supporting the main components such as the drilling rig, powerhead, and guiding elements for drill rod insertion.
4. Slewing Mechanism:
The slewing mechanism, consisting of the boom, outriggers, supporting legs, slewing cylinders, mast, and slewing cylinders, allows for the easy adjustment of the central axis of the powerhead and the working range of the mast.
5. Powerhead:
The powerhead is equipped with two sets of Rexroth hydraulic motors, a gearbox, and shock absorbers. It serves as the powerhouse for the rotary drilling process.
6. Telescopic Drill Rods:
The drilling process relies on telescopic drill rods, available in friction and interlocking types. These rods provide the necessary extension for reaching various depths.
7. Hydraulic System:
Utilizing a dual-circuit control with pilot operation, the hydraulic system consists of a high-pressure, high-flow main hydraulic system, a medium-pressure, low-flow auxiliary hydraulic system, a low-pressure pilot system, a cooling system, and a lubrication system for the powerhead.
8. Electrical System:
Incorporating a two-tier distributed control structure with CANbus technology and virtual instrument displays, the electrical system employs embedded controllers and vibrant LED screens for seamless programming and control.
Understanding the multifaceted components of a rotary drilling machine sheds light on the intricate synergy that powers these machines for efficient foundation work. From the robust crawler chassis to the advanced hydraulic and electrical systems, each element plays a crucial role in achieving precision and productivity in construction projects.
